Description

The invention relates to geodetic instrumentation, namely, devices for measuring distances traveled on the ground by vehicles.

The purpose of the invention is to improve the accuracy by increasing the reliability of the results of measuring the distance traveled and expanding the range of application of the device.

Fig. 1 is a diagram illustrating the principle of distance measurement; in fig. 2 shows the layout of the application and reading units for the marking agent.

The device comprises a unit 1 for applying a marker agent, elements 2-9 of a reading unit and a processing unit 10.

The device works as follows

At the beginning of the journey, the marking agent is applied by block 1 to the ground, the starting signal of the engine or manual start can be the starting signal. When moving, the marking agent is successively considered as elements 2-5 or 6-9, depending on the direction of movement, and after reading the marking agent by elements 3 and / or 5, (7 and / or 9) a new recording of the marking agent is performed.

The reading of the marking agent 3 and 5 or 7 and 9 allows determining the number of integer distance from the marking agent application unit 1 to the reading element 3 or 7 of the marking agent. If during the next cycle the marking agent was not applied by block 1 and then was not read (or simply was not read) by elements 3 or 7, then elements 5 or 9 read the previous application to the marker

a bad agent and a coma. will be served to start unit 1 for the next application of the marking agent.

The intervening elements of the readout unit serve to accurately determine the domainer unequal to the whole application, and the measurement accuracy depends on the number of intermediate arcs.

The use of this invention in automated systems for topographic surveying of the terrain, automatic altimeter, topograms and other devices will reduce the measurement error of the distance traveled, increase the reliability of measurements and expand the range of application by using the device when moving along an arbitrary shape trajectory.
